Greater soil carbon and nitrogen in a Mojave Desert ecosystem after 10 years exposure to elevated CO2

Autor: R. Dave Evans, Benjamin A. Harlow, Akihiro Koyama

Publikováno v: Geoderma. 355:113915

We investigated patterns and possible mechanisms in the greater soil organic carbon (SOC) and total nitrogen (N) after 10 years exposure to elevated atmospheric CO2 concentration ([CO2]) at the Nevada Desert FACE Facility, USA, reported by Evans et a

The response of terrestrial ecosystems to climate change remains a large source of uncertainty in the global carbon budget. Now results from a ten-year ecological manipulation experiment in the Mojave Desert provide direct evidence that CO2 fertiliza

Nitrate–nitrogen and oxygen isotope ratios for identification of nitrate sources and dominant nitrogen cycle processes in a tile-drained dryland agricultural field

Autor: Benjamin A. Harlow, Jeffrey L. Smith, C. Kent Keller, Cailin H. Orr, R. D. Evans, Christopher J. Kelley

Publikováno v: Soil Biology and Biochemistry. 57:731-738

Agricultural systems are a leading source of reactive nitrogen to aquatic and atmospheric ecosystems. In this study environmental δ 15 N nitrate and δ 18 O nitrate are used to identify the dominant nitrogen cycle processes and sources of NO 3 − l

Analysis of low-concentration gas samples with continuous-flow isotope ratio mass spectrometry: eliminating sources of contamination to achieve high precision

Autor: Nerea Ubierna, R. David Evans, Maria O. L. Cambaliza, Benjamin A. Harlow, John D. Marshall, George H. Mount

Publikováno v: Rapid Communications in Mass Spectrometry. 23:3868-3874

Developments in continuous-flow isotope ratio mass spectrometry have made possible the rapid analysis of delta13C in CO2 of small-volume gas samples with precisions of or = 0.2 per thousand). VBF was optimal for the preparation of gas samples, as it

A multi-species comparison of delta13C from whole wood, extractive-free wood and holocellulose

Autor: Benjamin A. Harlow, John D. Marshall, Andrew P. Robinson

Publikováno v: Tree physiology. 26(6)

The stable carbon (C) isotope composition (delta13C) of tree rings is a powerful metric for reconstructing past physiological responses to climate variation. However, accurate measurement and interpretation are complicated by diagenesis and the trans

Leaf longevity of western red cedar (Thuja plicata) increases with depth in the canopy

Autor: John D. Marshall, Benjamin A. Harlow, Remko A. Duursma

Publikováno v: Tree physiology. 25(5)

Leaf longevity determines the annual cost of replacing foliage biomass and influences water and nutrient budgets. Longevity is readily estimated in most evergreen species by annual bud scars along the shoot. However, some species with indeterminate g
